dexDebug ExecException finished with non-zero exit value 2

這個問題, 好像大都是超過65536個函數所引起, 所以只要想辦法減少函數數目或在build.gradle中宣告

multiDexEnabled true 即可解決

android {
    compileSdkVersion 23    buildToolsVersion "23.0.2"
    defaultConfig {
        applicationId "com.myapplication"        minSdkVersion 16        targetSdkVersion 23        versionCode 1        versionName "1.0"        multiDexEnabled true    }
....
